METALLIC FRAMING FOR CONCRETE TANKS.

SPECIFIGATION forming part of Letters I Patent No. 737,500, dated August25, 1903.

' Application filed December 16,1902. Serial No. 135,430. (No'modeL) Toall whom it may concern:

-Be it known that we, JOHN W. SEAVER and JAMES E. A. MOORE, bothcitizens of the United States, and residents of Cleveland,

Ohio, have invented certain Improvements in Metal Framing for ConcreteTanks, of which the following is aspecification. Our invention relatestothe construction of tanks having a body of concrete or other materialwhich while in a plastic condition can be molded into shape upon ametallic supporting frame or skeleton, one object of our invention beingto simplify and cheapen the construction of this metallic framework,especially in the case of tanks havingconical, semispherical, or othertapering bottom portions, and a further object being to so construct themetallic framework that all of the pieces composing the same-will be oflimited weight and size, so that it can be readily stored, transported,or assembled, the fieldwork on the frame being of the simplest possiblecharacter. g

In the accompanying drawings, Figures 1, 2, 3, and 4 areverticalsections of portions of tanks constructed in accordance with ourinvention; and Figs. 5, 6, 7, and .8 are plan views of quarter-sectionsof the metallic framework of the tanks shown in Figs. 1, 2,

3,'and 4, respectively.

We have shown our invention asapplied to a circular tank with tapering-loottom,'but said invention in its broadest form is not limited tocircular tanks, although the tapering bottom will in most cases beretained.-

The tank is supported upon vertical columns connected by means ofhorizontal tie-rods, these columns supporting a circular or othersurrounding girder which is suitably secured to the columns and maybemounted there upon in different ways,either by recessing the column 'forthe reception of the girder, by

recessing the girder for the reception of a por-' tion of the column, orby forming the girder in segments rigidly secured to the column. To thisgirder are attached rods which support the bottom of the tank, and thegirder is stayed or supported by means of vertical rods embedded in theconcrete or other material forming the sides ofthe tank, these rodsbeing by preference connected to a top girder which is suitably securedto and carried by the supporting-columns. I

In Figs. 1 and 5 of the drawings, 1 represents one ofthe-supporting-columns of the tank; 2, the circular girder; 3, thehorizontal rods whereby one column is connected to another; 4, theVertical supporting-rods embedded in the-concrete body of the tank, and5 the circulartop girder vto which the said vertical rods are connected.In the present instance this connection is effected by passing the rodsthrough openings in the girder 5 and providing their threaded upper endswith nuts -6, bearing upon the top of the girder. The rods 4 areconnected to the girder 2by means of yokes or clips 7, the legs of whichpass through openings in the girder and are threaded for the receptionof nuts 8, whereby they are secured to said girder; but other means thanthese may be adopted for securing the vertical rods 4 to either. of thegirders. The girders 2 and 5 and the rods 3 and 4 thus form a strong andrigidly-braced body structure, all engaging parts of which lend eachother mutual support.

The tank shown in Figs. 1 and 5 has a semispherical bottom with centralopening, and the rods which support said bottom consist in part of'continuations 45 of the Vertical rods 4, these rods being continueddownwardly to an annular bar 9, embedded in the concrete bottom-of thetank, to which bar 9 the lower ends ofthe rods 4; are secured. From thebar 9 to a flanged bar 10, which sur rounds an opening in the bottom ofthe tank, extend other rods 11, suitably secured both to the bars 9 and10, and those portions of the rods 4 which extend between the circulargirder 2 and the bar 9 are stiffened by means of horizontal lattice-rods12.

In the tank shownin Figs. 2 and 6 the girder 2 is of box form instead ofbeinga simple channel-bar, as shown in- Figs. 1 and 5, and the bottom ofthe tank is of parabolic instead of semispherical form. The bottombrace-rods 4? in this tank are separate from the verticalsupporting-rods 4 of the sides of the tank, and the top member of theboxgirder 2 has inclinedlugs, forming seats for nuts at the upper endsof the rods 4:. The rods extend directly from the girder 2 to the bar10, surrounding the bottom opening of the tank, and they are braced bytwo sets of horizontal lattice-rods 12.

The tank shown in Figs. 3 and 7 has a conical bottom which is braced byrods 13, secured at their lower ends to the bar 10 and hooked at theirupper ends for engaging with the loops of a series of looped or bentrods 14, the upper ends of which pass through the girder 2 and receivenuts bearing upon inclined lugs on the top of said girder, whereby thevarious parts may be maintained under proper tension. upon the loopedends 14 just above their connection with the hooked ends of the rods 13.

The tank shown in Figs. 4 and 8 embodies a further extension of thelooped-rod idea, the lower hooked rods 13 in this case engaging anintermediate 'set of looped rods 16,

. whose upper ends are hooked for engagement with the upper set oflooped rods'14, the latter being secured to the girder 2 in the samemanner as the corresponding rods of Figs. 3 and 7, the girder 2 in thiscase, however, being a box-girder instead of the channel-bar girdershown in Fig. 3. Horizontal stiffeningrods 17 and 18 are in this casedisposed adjacent to the looped ends of the rods 14 and 16.

In the tanks shown in Figs. 3, 4, 7, and 8 the number of bracing-rods inthe bottom increases in proportion to the increasing diameter of thebottom. Hence a more uniform support for and bracing of all portions ofthe bottom is provided than where the bottom has the same number ofbracing-rods throughout.

In all of the forms of metallic framework which we have shown the partsare simply ordinary merchant rods, bars, or plates, and the erection ofthe framework involves nothing more than the application of nuts to thevarious rods or bolts after the latter have been put in place. Theparts, moreover, are all relatively small in size'and lightin weight.Hence they can bereadily transported, and the tanks can consequently beerected without the employment of skilled labor and in any desiredlocality irrespective of its difficulty of access.

Having thus described our invention, we claim and desire to secure byLetters Patent-- 1.
